摘要：
A method, a non-transitory computer-readable storage medium, and an image processing apparatus are provided for performing iterative reconstruction to generate a medical image. The method includes generating, by circuitry of the image processing apparatus, a first image data set by separately back projecting subsets of a first view data set. Each of the subsets of the first view data set corresponds to one of a plurality of different non-overlapping sections of the medical image to be reconstructed. The method further includes generating, by the circuitry, a second view data set by separately forward projecting subsets of the first image data set. Each of the subsets of the first image data set corresponds to one of the sections of the medical image to be reconstructed. Further, the step of generating the second view data set starts before the step of generating the first image data set is completed.
